It's a balancing act, one done with considerable finesse. Perhaps that's because the two genres blend so naturally with each other that you aren't completely aware of its hybrid nature. You can approach Eastern Shadows from an intellectual angle, uncovering those Balkan influences and determining how they take the music in a different direction, or you can just go with the flow and take it at face value--intriguing, well-played jazz with exotic touches right around the edges.
